7月6日上午10点20分左右，位于广西南宁横州市的六蓝水库发生溃坝灾害[1]。坝体被撕开两处约50米宽的缺口[1]，截至7月9日，造成26人死亡、7人失联[1]。
中国国务院随后成立溃坝灾害调查评估组进行调查[1]。7月24日，调查评估组召开第一次全体会议，由应急管理部副部长陈敏主持[1]。会议强调按照科学严谨、依法依规等原则全面查明灾害原因和责任[1]。
六蓝水库建于1958年"大跃进"期间[1]，事故发生前一年才完成标准化管理工程[1]。根据相关统计，中国在1958至1965年间建成水库4万5410座，其中210座为大型水库[1]。
A major dam failure struck Guangxi Province on July 6, when the Lanliu Reservoir near Hengzhou in Nanning catastrophically breached, creating two gaps approximately 50 meters wide in the dam wall.[1] The disaster resulted in 26 deaths and 7 people listed as missing as of July 9.[1] The reservoir, originally constructed in 1958 during China's Great Leap Forward period, had completed standardized management engineering work only one year prior to the collapse.[1]
In response to the disaster, China's State Council established an investigation and assessment team to examine the causes and assign responsibility for the incident.[1] The group convened its first plenary session on July 24, chaired by Chen Min, deputy director of the Ministry of Emergency Management, with officials emphasizing a commitment to conducting a comprehensive, scientifically rigorous investigation in accordance with legal procedures.[1] Historical records indicate that China constructed approximately 45,410 reservoirs between 1958 and 1965, of which 210 were classified as large-scale projects.[1]
